He's not. He's probably not appreciably worse, either. But when you get down the depth chart like that, things other than the ability to run around the football field come into play. Coaches want to know that you can study the play book and learn the offense enough to come in at a moment's notice and at least give the guys around you a chance to win. VY doesn't have that.
I'd take Mr. Checkdown. At least he knows where the outlet receiver is and he won't turn the ball over much. It'd be a defense and running game type of game. Furthermore, I think NFL coaches would take Carr over VY, because they know they can plan around his limitations. VY out there is just too much of a wild card for them. Coaches are control freaks like very few others.
